The idea is to use the tangent line to at
in order to approximate
.
We have
so the linear approximation to is
Hence and
.
Then
Expand and simplify 2(5x - 1) – (2x - 5)

sorry to answer late but..
Step-by-step explanation:
=
the wings of the real plane are 12 meters or 1200 cm
we want to solve for the scale, sooo do the algebra...get scale by it self..
real * = scale
1200 * = 16
The scale model wings are 16 cm 2.54 cm is one inch so the wings are approx. 6.3 inches
